Re: Question for the DNS system.

[Donald Eastlake 3rd <dee3 at torque.pothole.com>]

Deep (many label) DNS names work fine. But for some reason the DNS
system has long suffered from lust for the root where people scramble
for DNS names with the minimum number of labels. This, coupled with the
marketing efforts of some TLD owners resulting in very wide zones that
require huge servers, are harder to deploy DNSSEC on, etc. It's wide
zones that are a potential problem, not deep names.

(There is some logic in going for short domain names interms of total
number of characters or ease of memorization. But based on that,
1.2.3.example would be superior to onetwothree.example. Yet people lust
after the second...)

Thanks,
Donald
